KTM RC 125 Full Specifications and Features

The KTM RC 125 is powered by a 124.7cc single-cylinder, liquid-cooled, 4-valve DOHC engine - the same bottom end that powers the KTM 125 Duke. It produces 14.5 PS at 9,250 rpm and 12 Nm of peak torque at 8,000 rpm, mated to a 6-speed gearbox. ARAI-certified fuel efficiency stands at 41 kmpl, and real-world city usage typically returns 36-39 kmpl depending on how hard you ride.

What makes the RC 125's spec sheet special isn't the engine - it's everything around it. The front end gets 43mm WP APEX open-cartridge USD (upside-down) forks - the same units fitted to the RC 200. At the front wheel sits a 320mm petal disc gripped by a radially-mounted 4-piston BYBRE fixed caliper, a setup you'd more commonly see on mid-displacement sportbikes. The rear uses a 230mm disc with a single-piston caliper. Single-channel ABS is standard.

The chassis is a steel trellis frame identical to the one used in the RC 200 and RC 390, giving the 125 genuinely responsive steering and composed mid-corner stability. Wheelbase is 1,340mm, rake is 22.5 degrees, and the overall geometry is race-oriented - this is not a comfort-first setup.

Kerb weight is 160 kg and seat height is 824 mm, which makes it approachable for most Indian riders in the 5'5" - 6'0" range. The 13.7-litre fuel tank is inspired by KTM's RC4 race bike and is the largest in the 125cc class. Tyres are MRF Revz radials - 110/70 R17 front and 150/70 R17 rear - on 17-inch alloy wheels.

The RC 125's standout spec is its hardware-per-rupee equation on the chassis side. No other 125cc sportbike in India gives you USD forks, radial brakes and an RC390-derived trellis frame. The trade-off is ergonomics - the fully-faired, tucked-in position is true to the race-bike inspiration and will fatigue your wrists and back on long urban slogs. If you're planning to spend most miles on open roads or a track day, the RC 125 rewards you. If the bike mostly sits in Delhi traffic, your body will ask questions your brain won't want to answer.

Frequently Asked Questions

QWhat is the engine displacement of the KTM RC 125?▾

QWhat is the fuel efficiency of the KTM RC 125?▾

The KTM RC 125 delivers an ARAI-certified fuel efficiency of 41 kmpl. In city riding conditions, real-world efficiency ranges between 36-39 kmpl, while highway cruising returns 42-45 kmpl. The 13.7-litre fuel tank gives an estimated range of approximately 500 km between fill-ups.

QWhat are the dimensions and kerb weight of the KTM RC 125?▾

The KTM RC 125 has a kerb weight of 160 kg, a seat height of 824 mm, and a wheelbase of 1,340 mm. Overall dimensions are 1,988 mm (length) × 820 mm (width) × 1,098 mm (height). The 824 mm seat height is manageable for riders above 5'5" tall.

QDoes the KTM RC 125 get ABS?▾

Yes, the KTM RC 125 comes with single-channel ABS as standard. It operates on the front wheel, paired with a 320mm disc and a 4-piston radially-mounted BYBRE caliper. The rear uses a 230mm disc with a single-piston caliper but no ABS.

QWhat suspension setup does the KTM RC 125 use?▾

The KTM RC 125 uses 43mm WP APEX open-cartridge USD (upside-down) forks at the front - the same units fitted to the RC 200 - with 150mm of travel. The rear gets a WP APEX monoshock with adjustable preload. This hardware is shared with higher-displacement RC siblings and is the single biggest differentiator versus Japanese 125cc rivals.
